[HELP] Triple combination of buttons at a time - Not working

[Trokinos]

No idea for phones, but for PC, you can setup a specific game config for your game and change your controls so you assign the same key to several psp control

By example, if you assign the key Q to the X, O and Triangle actions, if you press Q during the game , it will consider you will have pressed X, O and Triangle at the same time.
